摘要： In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc, into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.

摘要： Systems, methods, and other embodiments associated with any-to-any multicasting in a tunnel based virtual private network (VPN) are described. One example method includes calculating a resolved address for an unknown reverse path forwarding (RPF) neighbor in an any-to-any multicasting route. The resolved address is calculated using next hop resolution protocol (NHRP) resolution. The address is to be resolved based on control plane traffic. The NHRP address resolution is not to affect unicast routing. The example method may also include establishing the any-to-any multicasting route. Since the multicasting route is any-to-any (e.g., spoke-to-spoke), the multicasting route is not required to include a hub in the logical hub-and-spoke network.
摘要翻译：描述与基于隧道的虚拟专用网（VPN）中的任何多播相关联的系统，方法和其他实施例。一种示例性方法包括计算任何到任何多播路由中的未知反向路径转发（RPF）邻居的解析地址。使用下一跳解析协议（NHRP）分辨率计算解析的地址。该地址将根据控制平面流量进行解决。 NHRP地址解析不影响单播路由。示例方法还可以包括建立任何到任何多播路由。由于多播路由是任何到任意的（例如，辐对话），所以组播路由不需要将集线器包括在逻辑集线器辐射网络中。

摘要： A method is provided in one example implementation and includes sending a PIM join message to the second spoke router by the hub router. The second spoke router dynamically determines each interested remote spoke router by parsing a hub-sent PIM message and accordingly constructs the multicast routing entry such that the first and second spoke routers establish multicast communication independent of a hub router. In more specific embodiments, the PIM join/prune messaging includes a list of each downstream spoke router that sent a PIM join/prune, in a new attribute. The PIM join/prune message is sent by the hub router towards a multicast source. A new receiver-list attribute is created that the hub router populates with a non-broadcast multi-access (NBMA) address for each interested spoke router.
摘要翻译：在一个示例实现中提供了一种方法，并且包括由集线器路由器向第二分支路由器发送PIM加入消息。第二分支路由器通过解析集中发送的PIM消息来动态地确定每个感兴趣的远程分支路由器，并因此构建多播路由条目，使得第一和第二分支路由器独立于集线器路由器建立组播通信。在更具体的实施例中，PIM加入/剪枝消息包括在新属性中发送PIM加入/剪枝的每个下游分支路由器的列表。 PIM加入/剪枝消息由集线器路由器向组播源发送。创建一个新的接收者列表属性，集线器路由器为每个感兴趣的辐条路由器填充非广播多址（NBMA）地址。

摘要： In one embodiment, a network device joins a first multicast tree to receive post-ad-inserted video content. The network device also joins a second multicast tree to receive the pre-ad-inserted video content. The content from the first multicast tree is forwarded by the network device to the receiver(s). The network device determines if it does not receive the content on the first multicast tree due to any failure, in which case, it delivers the content from the second multicast tree to the receiver(s). This enables the receiver to receive the original (pre-ad-inserted) content during the failure in first multicast tree. When the failure is resolved, the network device can go back to sending the content from the first multicast tree to the receiver(s).
摘要翻译：在一个实施例中，网络设备加入第一多播树以接收插入后的视频内容。网络设备还加入第二多播树以接收预先插入的视频内容。来自第一多播树的内容由网络设备转发给接收者。网络设备由于任何故障而确定它是否在第一多播树上不接收内容，在这种情况下，它将内容从第二多播树传送到接收者。这使得接收机能够在第一个多播树中的故障期间接收原始（预先插入的）内容。当故障解决时，网络设备可以返回将内容从第一多播树发送到接收者。

摘要： In one embodiment, a Home Agent receives a Mobile IP registration request from a group member, where the group member is a Mobile Node. The Home Agent generates a mobility binding for the group member that associates the group member with a care-of address, wherein the group member is a member of one or more groups. The Home Agent generates a Mobile IP registration reply, where the Mobile IP registration reply identifies one or more key servers. Each of the one or more key servers serves at least one of the one or more groups and is adapted for distributing group cryptography material to members of each group that is served by the corresponding key server. The Home Agent sends the Mobile IP registration reply to the group member, thereby enabling the group member to obtain cryptography material for at least one of the one or more groups from at least one of the one or more key servers to enable the group member to use the cryptography group material to securely communicate with other group members.
